A Rebuttal

By Keith Kloor | March 8, 2013 9:03 am

The cover story in the April issue of Discover is about the anti-GMO movement in Europe.


I found it interesting but also narrowly centered on the opposition in Germany. For example, the piece neglects to discuss, much less mention, a widely publicized event last summer involving a UK government sponsored research lab. This featured UK scientists mounting a public campaign to dissuade anti-GMO protesters from destroying their research. It was unprecedented and powerfully effective. The clash between the two sides played out for weeks, made headlines around the world, and led to a public reexamination of the anti-biotech cause (at least in Britain). To me, any discussion today of the “crop wars” in Europe needs to include this watershed battle.

I also have a few other things to nitpick about the Discover article (which you can read for free, after registering at the site), but I’ll leave that for another day. Meanwhile, let me turn to a sidebar piece accompanying the feature. It is about the growing opposition to GMOs in the United States. In my opinion, this short article has major shortcomings. And I’m being polite when I say that.

When I drew attention to the piece via Twitter yesterday, there was near instantaneous shock and outrage to it from some scientists. Others also shook their heads in disbelief. This included Rachael Ludwick, a software developer who is passionate about science and agricultural issues. Ludwick is a smart, articulate communicator who participates frequently in science-based forums that focus on biotechnology. Initially, I had thought to express my own reservations about Discover’s sidebar piece. But then I asked Ludwick to offer a rebuttal, which follows below. 


The Discover headline was so promising: “Anti-GMO Grass-Roots Effort Gains Ground in U.S.” I hoped it would be about just how strange the alliances in the anti-GMO movement are. We have groups like the Environmental Working Group and the Union of Concerned Scientists working alongside organic industry boosters and organic food companies. And then there are the (louder and shriller ) groups that claim dire risks from GMO foods. So this opposition in the U.S.  is a topic that deserves closer examination.

Instead, what I found is a piece that repeated–almost without challenge–misleading claims about GMOs stated by anti-GMO activists. Most of these claims are at best half-truths. Let me be up front: I can’t write about everything I think is misleading in this piece. There’s just too much. But, there are a few ideas that are repeated uncritically which are far more interesting than this piece lets on.

Probably the most common claim of anti-GMO activists is that GMOs are untested and unsafe. Charles Benbrook, an organic proponent (why is a proponent of organic and opponent of GM merely labeled an “agricultural policy expert”?) is quoted in the story saying that the “science just hasn’t been done.” That’s just not true. There are hundreds upon hundreds of  studies. Genetically engineered crops are some of the few foods tested before they come on the market and all the data is on the EPA’s website. This testing is not typically the case for non-biotech foods. In the 1950s, the kiwi fruit was introduced to the U.S. without testing. We’ve since learned that it’s allergenic. More recently, new celery varieties have resulted in contact rashes in workers due to increased amounts of natural toxicants called psolarens (similarly, new potato varieties sometimes develop excess toxic solanine).

But there’s a kernel of truth behind the not tested claim. David Schubert (who is cited in the piece as a biologist without noting his association with the anti-GMO campaigner Jeffrey Smith) is very careful when he says: “no significant safety testing is required by FDA.” That is absolutely true. All safety testing done on GMO crops is voluntary. But even though it’s voluntary, every company has complied! The lack of mandatory testing does unnecessarily worry people: what good is the FDA if it can’t even require safety testing for food? This is perhaps why the American Medical Association recommended mandatory safety testing, despite also saying current GMO foods are safe and labeling is unnecessary. Pre-market testing should probably be mandatory, but it’s just not the case that GMOs are untested before going to market.

GMO foods are also subject to repeated studies by scientists after they come on the market for toxicity and other risks. Overwhelmingly, these studies show no problems for human health. You wouldn’t know that from the Discover piece, since it chose to mention problems found by a small minority of researchers, often heavily criticized. The piece wiggles around this issue by noting it’s hard to prove a causal link in humans. The reality is that links aren’t even proved in animals.

But what about those “superweeds” mentioned in the piece? And that toxic Roundup? There’s context missing here too. Roundup is indeed toxic; to most plants and marginally to some animals; but it is one of the safer herbicides we have. While the term “superweeds” is not one scientists use, preferring phrases like “herbicide resistant,” they are a real problem. We have seen an increase in weeds resistant to glyphosate (the active ingredient in Roundup). But what the Discover piece is not telling us is that this is normal and expected: any herbicide used heavily for years will naturally select for weeds that can survive it. The most important missing context though, can be found in this graph, which shows cases of herbicide resistant weeds, grouped by site of action.

One herbicide deserves special mention. Atrazine (a member of the triazine family) doesn’t harm corn, so it’s been used for decades to control weeds in corn fields. Unsurprisingly, that class of herbicides has had significant weed resistance for much longer than Roundup. The point here is emphatically not to deny the problem of herbicide-resistant weeds. That is a real problem. But it’s not a problem with genetically engineered crops per se, but with management practices. Roundup Ready crops could have been banned ten years ago and farmers would still have weeds resistant to herbicides. You just wouldn’t hear about them from anti-GMO campaigners.

There’s a real story in the alliance of anti-GMO groups and how, in the United States, they are using the political system, instead of vandalism (as in Europe) to advance their agenda. This story isn’t it; instead, it prefers to repeat myths and exaggerations about GMO foods in a one-sided manner.

There are some good questions about GMO activism springing up in the U.S. For example, why do organic food growers care so much about labeling GMO ingredients when transgenic crops are not allowed in organic products?  Why is the anti-GMO campaign only now gaining traction in the United States? What’s behind that? Those would be interesting questions to explore in a story.

    Good post.

    After you’ve been around the block you can read lines like this and laugh:

    “But since these products aren’t labeled or tested by impartial scientists…”

    Hmmmm…wonder what “impartial” means here? Possibly defined as scientists who only conclude GMO’s are dangerous? It is a standard disinformation tactic. Infer testing isn’t being done, but use a vague qualifier that eliminates everything you disagree with. Obviously testing is being done, they talk about it two lines later.

    Time to stop reading after you get to stuff like this.

    “Today, about 75 percent of processed foods contain genetically engineered ingredients…”

    “There is no credible evidence that GMO foods are safe to eat…”


    Obviously KK has to be careful here, but this kind of garbage should never make it to print in a science magazine. I’m not saying they should not have a voice, but it should at least be held up to some kind of standard. On the other hand, they come off as buffoons, so it isn’t all bad.

    Who needs to dwell on GMO myths when their most egregious acts are conniving and deviously hiding in plain sight crowing GMO-normal-food-sameness whilst simultaneously prosecuting contaminated farmers for infringing upon their patented trait? GMOs are the seed of an immoral industry and sham science, guarding their flanks with legal infantry, commandos and capital artillery.

    • http://twitter.com/r343l Rachael Ludwick

      So, if I’m understanding what you write here, it’s fine for activists to exaggerate and mislead about GMOs because some people are bad actors? Note, I think you exaggerate, but even if these claims were perfectly true, surely activists should focus on those and not make things up?

        The main disadvantage of many ge seeded products is the tendency to continue the traits overwhelmingly to the next generation. Farmers used to collect seed for the next crop, and are penalized severely by patent owning companies. We just can’t be thrifty anymore.

        • http://twitter.com/r343l Rachael Ludwick

          In the case of corn, they did not actually tend to save seed because hybrids have been improving yields dramatically for most of the 20th century. But I’m not sure how that’s relevant to whether it’s okay to mislead about GMO safety in lieu of talking about actual problems in the agriculture industry (that easily apply to non-GMO production in many cases …)

    It intrigues there was no mention in the article of Mark Lynas’ public mea culpa in early January at the Oxford Farming Conference on his years of mistaken opposition to GMOs. It was well publicized at the time. This below from Andrew Revkin at Dot Earth…(there were many others)


    I guess to include this development would have undermined the premise of the “Crop Wars” article. To wit:


    “I want to start with some apologies. For the record, here and upfront, I apologise for having spent several years ripping up GM crops. I am also sorry that I helped to start the anti-GM movement back in the mid 1990s, and that I thereby assisted in demonising an important technological option which can be used to benefit the environment….”

    • http://twitter.com/r343l Rachael Ludwick

      To be fair, the sidebar that is of greatest concern is about the United States and Mark Lynas isn’t really a big name here. I can understand them leaving that out.

  • Lynn Dewees

    Personally, I don’t really care one way or the other about GMO, but why are the companies that make it so afraid of labeling? Why shouldn’t people be allowed to know what they are eating?

    • jh

      ONE: As Keith pointed out, there are already non-GMO options clearly labeled: organic.

      TWO: Since there is no credible evidence that GMOs are harmful, there doesn’t seem to be any reason to label.

      THREE: I don’t want to pay for food companies to do the accounting.

      The objective of the GMO labeling movement is to create a scare that drives sales of the much pricier and higher-margin organic.

    Hello Rachel. How are you?
    GMO foods are also subject to repeated studies by scientists after they come on the market for toxicity and other risks. Overwhelmingly, these studies show no problems for human health.

    Do you realize that the first link takes you to:


    You don’t have permission to access /genera/studies-for-genera/independent-funding/ on this server.

    Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

    And the second link to the review in no way shows safety of GMOs in people?

    There are several reasons for that.
    1. You need to read the entire article and all the studies in the review, half of which are shitty sloppy industrial studies
    2. Half the studies cited do indeed suggest harm
    3. None of the studies are on humans, and thus by definition can not demonstrate lack of harm to human beings.

      The five studies using maize (Hammond et al., 2004,2006a,b; Mackenzie et al., 2007; Malley et al., 2007) found no differences

      which did not. These studies concluded that the maize grain tested

      The safety assessment of genetically modified (GM) food and feed is performed to identify the possible effects upon animal and human health, also the long-term, multigenerational influence upon functioning of different organs and systems, such as the immune system. In this study C57BL/6J mice were fed for five consecutive generations with pellets containing 20% of conventional triticale grain (control) vs.
      pellets containing 20% of the transgenic triticale grain resistant to BASTA herbicide (experimental). The F5 experimental animals showed enlarged inguinal and axillary lymph nodes, but not spleens, and increased WBC counts in blood (but within the norm for Mus musculus). Immunophenotyped cell suspensions
      derived from spleens, inguinal and axillary lymph nodes and PBMCs from blood showed the significant decrease in the percentage of T cells in spleen and lymph nodes and the B cells in lymph nodes and blood of the F5 experimental mice in comparison to the control F5 mice.
      Immunoblotting analysis of IL-2, IL-4, IL-10, IL-12, IL- 6, IFN-gamma levels in serum showed significantly increased IL-2 levels and decreased IL-6 levels in the F5-experimental mice sera. No significant changes in the levels of IgE in sera in both mice groups
      were observed. The obtained results indicate that multigenerational use of feeds for rodents containing the GM-triticale leads to expansion of the B cell compartment in the secondary lymphoid organs, but it is not caused by malignant processes or the allergic response.


      So, Rachael. Where in this study did you find any degree of certainty of safety of GMO foods to human beings, again?

      As for biofortified, it inconveniently started having technical troubles yesterday and I don’t know why (I don’t run the site). When I wrote the post it was up. I have a copy of the GENERA study database though, if anyone would like a copy.

        Rachael. I actually consider Kevin to be a good friend, and I do believe he knows that ( though admitting it publicly is a pretty tricky thing under these circumstances). What I respect the hell out of in Kevin is that he is indeed a scientist, who discusses specific discreet science. Whether we agree or disagree is not that important in the grand scheme of things– the discussions are illuminating as hell.

        I don’t blame you, Rachel, for refusing to engage on a biotech/ medical issue. I sure would feel like a fish out of water trying to discuss computers, but please don’t use silly excuses to avoid the discussion of SCIENCE you are clearly not trained to discuss without an intimate understanding of biotechnology and medicine, except by regurgitating back what someone spoon fed you.

        The truth is that you do not have a scientific rebuttal to the scientific questions I raised here on Discover, and you don’t have a rebuttal to the questions I raised on Kevin’s blog.
        The issue of the crummy safety ASSURANCE studies by Hammond et al hasn’t been touched with a ten foot pole.

        Malatesta’s work still stands and has not been dis-proven scientifically by anyone, because clearly if you use the idea that the work is flawed because the group didn’t use an isogenic line, you will have to discard half the studies in the review you cited.

        The question of shameful lack of empirical evidence to back up claims of absence of medical harm to people or animals ingesting these crops is the elephant in the room you are not prepared to touch. It was duly noted.

        Cheers. Have a great life.

          Hi Ena. Gosh, I do consider you a friend too. We have total internet Stockholm Syndrome. I think it is because you are clearly sharp and it is just a matter of time until you flip. You have to stop using that Maletesta work as evidence. It can’t be “dis-proven” because there’s nothing to prove in an experiment with one critical mistake– they don’ use the isogenic soy in their test, they use wild soy. The backgrounds in the experimental soy and the control are completely different. We know soy makes isoflavones and tons of other allergens and biologically active metabolites. It is not a good comparison.

          Be nice! I know I can be abrasive too, and have been, but it just makes these forums intolerable. Now that I have tons more work to do in my new position I don’t get to do this very often– and I think I’m much happier!

            Oh, come on Kevin. The scientific way to disprove Malatesta’s work is to replicate the experiment using an isogenic line of soybeans. We do have EMs and immuno-histopathologists in this country, don’t we?

          Ironically, you post this while conveniently ignoring the anecdotal evidence in the form of trillions of meals containing GMOs ingested by humans and the mind-boggling amount of GMO grain fed to the planet’s livestock over the last 18 years- which have still yet to produce a SINGLE instance of negative health effect. Its duly noted that you have elected to ignore this elephant in the room.

    It’s becoming clear that, regardless of the evidence, the argument for labeling is getting more traction and is probably going to be won eventually. I don’t care one way or the other whether GE products are labeled–I already know a lot about them. I think genetic engineering is one of those advances that make it interesting to be alive in the 21st century–yet it seems to me the industry is making a big mistake by not embracing the labeling movement

    I’m still convinced that labeling foods as GE will have the opposite effect the activists intend: It will point out as clear as day that people are eating ingredients from genetically engineered plants and going on to lead healthy, normal lives. It amounts to the best advertising one could hope for.

    The more industry resists and drags their feet, the more it’s going to look like they have something to hide. This is sadly how the politics work.

      I’m actually glad Whole Foods is going this route and I hope they can be lobbied to put more useful labeling in place: either per trait labels or even labels on a broader variety of agricultural practices (pesticides used, water use, etc.)

    The GMO hysteria ignores the entire history of human domesticated plants and animals. Every single food crop and most food animals have been genetically modified by humans over many thousands of years via selective breeding. Take corn…or maize as the Europeans and Amerindians call it. It was genetically modified over thousands of years from a small seed tassel. Original wild corn is still available today, and looks nothing like the large corn husks we are used to seeing in the grocery stores. It more resembles the tip of a wheat shaft. But over thousands of years, AmerIndians genetically modified it into a significant food crop, now grown over large parts of the world. The corn we plant today cannot even pollinate itself without human intervention. It cannot survive for long without human agricultural techniques. There are countless other examples of early human GMO work on other plants and animals: wheat, pigs, cattle, rice, barley, rye, etc.

    Get over the GMO hysteria. Scientists are only speeding up a process that humans have been using thousands of years…and if it weren;’t for GMO crops, India would be starving today, as GMO rice prevented Malthusian predictions from coming true and greatly multiplied the rice harvests in Asia to feed the growing population there.

    Quit fighting science. It is the only way we are going to continue to advance in this world, and keep increasing the quality of life for all of humanity. We can’t retrograde civilization back to the days of living in mud huts and subsisting entirely off the land as individuals. Industrial agriculture is here to stay. People are expanding the population of mega-cities, and more food is needed as a result.

      Richard Dickson, I would like to quarrel with you on one point. Your
      are skirting the issue when you say that genetic modification has taken place for centuries. It is true only in the scene of selective breeding techniques. My grandfather would survey his crop so he could harvest a portion of a field for seed for the next year. He mostly looked for more favorable yields. He might even trade some grain with his neighbors to select for some traits his crop didn’t display that year. He would observe favorable traits in his herd so to choose those animals that displayed what he would interpret as less work or more profits and breed for that through selective breeding. (which bull to introduce to which cow) Yes in the truest sense of the word he would alter or modify the gene set or at least
      modify how a gene displayed a trait.

      No but that is not what we are talking about here. When you
      crossbreed species that were never meant to be breed in the first place you are practicing modern GE. Inserting a cauliflower gene into a corn or soybean plant is not what has been done scene the beginning of time. Yes that plant might display the desired trait you were looking for but what else happened to that plant. Is it harmful to the public that ingest it? You don’t know. You don’t know until you follow the data on several generations of those that consume that plant. Those studies do not exist. If you disagree please quote the study. Most studies are done by the very company that is looking for an outcome. It’s the proverbial “fox holding the keys to the hen house”.

    When I read just how wrong Discover magazine have got this I am much more likely to pick up something else on the news stand. Countries that are crying out for these crops to feed their starving people while the west relaxes back in their armchairs pretending to be so righteous.

      The crops can also aid economic development. that can save lives.

    “This featured UK scientists mounting a public campaign to dissuade anti-GMO protesters from destroying their research. It was unprecedented and powerfully effective.”
    Keith, in terms of communicating in a calm, rational manner about the science around GMOs, I agree that this is a good thing. I know some people at Rothamsted and they are good, knowledgeable scientists. However, we in industry, universities and government research agencies should NEVER have to ask for our research NOT to be vandalized. In almost every case, these activities easily rise to the level of a felony.

    Genetically modified organisms do pose risks, as do organisms that have been altered through hybridization. Even natural selection has had some dangerous or undesirable results. It would seem the greatest risks are when modified organisms cross paths, or contaminate each others genetic lines. When naturally evolved organisms cross paths with a hardier modified, could we loose the slowly evolved version altogether?

    We’ve seen undesirable effects, for instance, in the hybridization of animals like dogs. “Pure breeds” are often afflicted with early onset of age related illnesses, not to mention some behavioral issues. Regression, or reversion, in hybrid lines can be fairly rapid, but I haven’t seen much data when it comes to reversion in genetically altered plant lines. Letting the genie out of the bottle is a very real concern when it comes to these short-cut methods. Natural selection can take millions of years, hybrids decades or thousands, but genetically modified organisms can be created in an instant, relatively speaking of coarse. Should caution be exercised? Without a doubt! Should people act like lawless mobs on a witch hunt? Certainly not!
    Real science is purposefully slow, in order to avoid unintended consequences. Much like a Medical Doctor’s oath “to due no harm,” as long as safeguards are put in place, man can benefit greatly from genetic research. Caution should be the focus for those on both sides of this argument.

    We overuse fluoride in our water supply, toothpaste, etc.. We are told that it is safe as well. However, nobody knows the true issues that fluoride can cause
    because there are no studies on it. Point is ignorance is among us and
    if nothing is done we will be praying to large corporations in a few

    So has Discover ever published an apology for their dishonest, unscientific articles about atrazine? I discontinued my subscription after their articles about evil atrazine and the wonderful Tyrone Hayes. Not only have real scientist not been able to replicate Tyrone’s research, his bizarre behavior is a good indicator of the quality of his work.
